Sethi said that you shouldn't assume you aren't passionate enough
about any particular issue to launch a thriving business.

"A lot of people wait for the passion to fall down from the
heavens," Sethi told Altucher. "Your passion doesn't fall down.
You find your passion."

How?

"You get passionate about something when you get good at
it," he said.

Sethi said that when he started out writing about personal
finance, he was still learning about it, which he openly
admitted. But as his knowledge grew and his writing improved, he
became more passionate about it. "I could watch people change,"
he said. "They started to invest; they saved money."

What's more, he said, simply having a topic you're passionate
about isn't enough. "Don't think that you're waiting for
lightning to strike and give you some passionate idea."

Anyone can have an idea, but an entrepreneur has to put in the
work to develop that idea, he added.

In other words, it's okay if you don't yet have a goal or a dream
that keeps you up at night. Actively pursue a few things you're
curious about or relatively skilled at and that passion will
develop over time.

It's not the most romantic idea — but it's possibly the most
realistic.
